I’ve only flown TAP on one trip in Business and it was in the before times and I thought the inflight service etc was more than fine.

The vast majority of people having issues with TAP are when trying to get refunds or compensation rather than with the onboard service.

how much of a pain is it getting to EWR over a change in AMS and with less good flight time?

I’d look at both the TAP and KLM boards for any recent inflight experience threads / comments.

but if you are wedded to using mikes then you really only have once choice.
